Etymology
From Medieval Latin epocha, from Ancient Greek ἐποχή (epokhḗ, “a check, cessation, stop, pause, epoch of a star, i.e., the point at which it seems to halt after reaching the highest, and generally the place of a star; hence, a historical epoch”), from ἐπέχω (epékhō, “to hold in, check”), from ἐπι- (epi-, “upon”) + ἔχω (ékhō, “to have, hold”). Doublet of epoche.
